In face-to-face conversation speech is perceived by ear and eye. We studied the prerequisites of audio-visual speech perception by using perceptually ambiguous sine wave replicas of natural speech as auditory stimuli. When the subjects were not aware that the auditory stimuli were speech, they showed only negligible integration of auditory and visual stimuli. When the same subjects learned to p...

Recent magneto-encephalographic and electro-encephalographic studies provide evidence for cross-modal integration during audio-visual and audio-haptic speech perception, with speech gestures viewed or felt from manual tactile contact with the speaker's face. Given the temporal precedence of the haptic and visual signals on the acoustic signal in these studies, the observed modulation of N1/P2 a...

The development of auditory-visual speech perception was investigated in pre-school children, school children and adults. Results show a link between auditory-visual speech perception and language-specific speech perception in school children. In addition it was found that speechreading ability in early childhood was predicted by cognitive abilities. Additionally, adults’ and preschool children...

When a speaker talks, the visible consequences of what they are saying can be seen. This auditory (the speech sound) and visual (movements of the lips and other articulators), or AV speech influences what listeners hear both in noisy listening environments and when auditory speech can easily be heard. Thought to be a cross‐cultural phenomenon that emerges early in typical language development, ...

objective: the aim of the present research was to compare the auditory perception and verbal intelligibility in children with cochlear implant, hearing aids and normal hearing. methods: 60 children aged 5-7 years were divided to three groups and each group contained 20 children. the first and second groups were selected ordinarily from children with cochlear implant and hearing aids by convenie...

Audiovisual speech integration combines information from auditory speech (talker's voice) and visual speech (talker's mouth movements) to improve perceptual accuracy. However, if the auditory and visual speech emanate from different talkers, integration decreases accuracy. Therefore, a key step in audiovisual speech perception is deciding whether auditory and visual speech have the same source,...

Auditory and visual information is integrated when perceiving speech, as evidenced by the McGurk effect in which viewing an incongruent talking face categorically alters auditory speech perception. Audiovisual integration in speech perception has long been considered automatic and pre-attentive but recent reports have challenged this view. Here we study the effect of visual spatial attention on...

Asymmetry in auditory cortical oscillations could play a role in speech perception by fostering hemispheric triage of information across the two hemispheres. Due to this asymmetry, fast speech temporal modulations relevant for phonemic analysis could be best perceived by the left auditory cortex, while slower modulations conveying vocal and paralinguistic information would be better captured by...
